Question

which of the following is the best description that matches the runoff from a stream pictured here? chemical weathering (reaction with water) mechanical weathering (frost wedging) erosion from water erosion from wind

Explanation:

• Chemical weathering involves a reaction of minerals with water to form new minerals.
• Mechanical weathering (frost wedging) is the physical breaking of rocks due to freezing and thawing of water in cracks.
• Erosion from wind is the removal of materials by wind action.
• Erosion from water is the process where water (like in a stream) transports and erodes sediments and rocks. The image shows a stream, so the runoff is related to water - based erosion.

Answer:

Erosion from water
